Verba

What it is

Verba is an open-source Retrieval-Augmented Generation (RAG) application built on top of Weaviate.

What problem it solves

It provides a user-friendly interface for building RAG applications, handling data ingestion, chunking, and querying with LLMs out of the box.

Where it fits in the stack

Category: Tool / Knowledge Management / RAG

Typical use cases
